Nebula Series By Ibiza anal plug in model 6 borosilicate glass

This time, you'll take the time to discover this anal plug from Nebula Series By Ibiza — a carefully crafted piece made of quality borosilicate glass. I haven't been able to test it personally, but after 10 years in the adult store business, I've seen plenty of glass plugs come and go, and I'll tell you something: it's a material that's often underestimated. Borosilicate glass is what we use in laboratories and professional kitchens, so you can imagine how durable it is. Zero porosity, maximum hygiene, and the ability to adapt to body temperature — or to be heated or cooled before use to vary the sensations.

Borosilicate glass material: durability and hygiene

Borosilicate glass isn't ordinary glass. Its chemical composition (boron instead of calcium) gives it exceptional thermal resistance. You can move this plug from cold water to hot water without risking cracks. It's nonporous — unlike TPE, TPR, or jelly materials — so bacteria and odors can't settle in it. Cleaning it with soapy water or in the dishwasher is that simple. No special treatment, no mandatory talcum powder, and no condom required if you use it alone. For me, this is a major advantage: durability and cleanliness without any hassle.

Dimensions and size: 12.5 cm for beginners or those progressing

This model 6 measures 12.5 cm in total length with a 4 cm diameter. It's a standard size — neither too thin nor intimidating. The wide base (which we'll discuss below) ensures it won't slip too far inside, which is crucial for anal safety. The weight of 230 g (transparent variant) or 234 g (pink variant) gives it a solid presence without being heavy. For someone beginning anal exploration, it's a good starting point. For more advanced users, it's a reliable companion for pure sensations without electronics.

Design and variants: transparent or pink

Nebula offers this plug in two colors: transparent and pink. The dimensions are nearly identical (with a slight weight difference: 230 g vs. 234 g, and slightly larger packaging for the pink version). The sleek, no-frills design reflects the brand's approach: functional beauty. The wide, slightly flattened base prevents any risk of loss, which really matters for anal use. Aesthetically, the transparent version lets you see the glass structure, while the pink offers a more discreet, colorful touch.

• Nonporous material, with no lingering odor
• Resistant to thermal shock (cold/hot water)
• Wide, secure base for anal use
• Two colors to choose from (transparent / pink)
• Easy to clean, dishwasher-safe

Lubricant compatibility and use

With borosilicate glass, you can use any lubricant: water-based, silicone-based, or even oil-based. There are no chemical reactions. I recommend a water-based lubricant for greater versatility and easier cleaning, but you have complete freedom. Anal play always requires lubricant — apply generously and slowly, without forcing. With this plug, you also benefit from glass's thermal conductivity: you can run it under lukewarm water for a few seconds before use for a gentler sensation, or cool it down for a pleasant contrast.

Who it's for and who it's not for

Who it's for: People looking for simple anal exploration without electronics, using a hygienic, durable material. Beginners seeking safety. People allergic to synthetic materials. Fans of temperature sensations (hot/cold). Those who want a “discreet” object to leave in plain sight (thanks to its sleek aesthetics).

Who it's not for: If you're looking for vibration, pulsing, or motorized stimulation, this passive plug won't meet that need — head to our vibrating dildo collection. If anal play makes you completely anxious, start with smaller accessories or less intense couples' activities.

Advice from a friend — Borosilicate glass is the choice for people who know what they want: hygiene, durability, and zero hassle. If you're hesitating between transparent and pink, go with your aesthetic instinct — the experience is identical; it's simply a matter of style.
